Why does fuse keep blowing on 2012 town and country Chrysler van seats
There is a short to ground somewhere in the circuit that the fuse protects. It could be one of the motors for the seats that has shorted out, or it could be on any wire that is on that circuit. Wires can get chaffed, or bent around edges and the insulation gets worn off. Then when the exposed power wire touches metal, it causes a spark, shorting to ground like that, and blows the fuse at the same time.
You will have to kind of track that circuit down. I would start at the motors on the seats, note where all the connections are, and follow the wiring path as best you can. You might try unplugging individual parts, like the individual motors or parts of the circuit where connectors are, and then see if a new fuse still blows, you may be able to track it down that way. Wherever the problem is, there is probably quite a bit of heat associated with the shorting. When you are feeling around, keep that in mind. Keep in mind also that without a wiring diagram, you can't be certain that the power seats are the only thing on that circuit. It is possible, maybe even probable, but you would need to verify it with a wiring diagram showing the power seats circuit. good luck.
